3 Please read prior to operation! NOTES ON SAFETY Warning: Do not exceed a pressure range of > 50 bar with standard version. With special versions up to 350 bar. Observe measuring ranges of sensor! The probes are damaged if they are overheated. Observe max. storage and transport temperature as well as max. operating temperature (e. g. protect measuring instrument from direct sunlight). Warranty claims no longer apply if the instrument is opened, in the case of inexpert handling or use of force. Adjustments or calibrations should be carried out by qualified measurement and control engineering staff only.! Important: Before installation briefly bleed the compressed air in order to remove condensate and particles. This prevents soiling of FA 510. Standing air leads to long measuring times. 3 DESCRIPTION The FA 510 dew point sensor enables a reliable and long-term stable monitoring of the dew point in industrial applications from -80 to +20 C dew point. The FA 510 features improved stability. When mounting FA 510 into compressed air systems the pressure dew point (dew point under pressure) up to 50 bar (in the special version up to 350 bar) is measured directly. When mounting FA 510 in atmospheric conditions (ambient pressure) or in the flow off sector (relaxed air) of compressed air systems the atmospheric dew point is measured. Advantages: Dew point sensor for very low dew points down to -80 Ctd Extremely long-term stable due to internal automatic calibration IP 65 housing grants a reliable protection in extreme industrial conditions Very fast response time Installable in the dryer by means of G 1/2" thread, optional UNF 5/8 or NPT ½ High accuracy of 2 Ctd Calibration on location and testing with CS control and calibration set (PC connection set) Programming via Software. With the CS Service Software incl. USB / Adapter the settings, the scaling of the Analogue output and the assignment of the measurement values could be set. - Analogue output 4 20 ma scalable - Switching between Ctd, Ftd, % RH, C, F, g/m³, mg/m³, g/kg, ppm, and so on - Calibration and adjustment - Sensor diagnosis - Read-out of service data

6 INSTALLATION Please note: CS recommends the indirect installation with measuring chamber Advantage: Easy mounting and dismounting of the probe without interruption of the line. Quick response time due to quick coupling. Optimum sensor protection. Indirectly in the compressed air system FA 510 Measuring chamber Standard connection compressed air pipe Connect probe with measuring chamber to the compressed air pipe by means of a quick coupling. In case of compressed air containing oil and dirt particles a pre-filter should be installed in front of the measuring chamber. Compressed air flows continuously (at 7 bar approx. 1 l/min expanded) in the capillary pipe of the measuring chamber. The reaction times for the humidity reading are shorter than in case of a direct mounting. compressed air pipe FA 510 Directly in the compressed air system Screw in probe with G 1/2" thread pressure-tight in the center or at the top of the compressed air pipe. Take care that measurement is effected close to the compressed air flow. U-bend pipes or non-flowing compressed air, result in very slow reaction times for the moisture reading. Measurable gases FA 510 In general, humidity can be measured in all noncorrosive gases. In case of measurements in corrosive gases please consult CS Instruments GmbH. 6

7 Register The dew point sensor FA 510 comes with a RTU Interface. Before commissioning of the sensor the communication parameters ID, Baudrate, Parity und Stop bit must be set in order to ensure the communication with the master. The adjustment can be done either with the CS Instruments PC service software, DS 400, DS 500 and the hand-held instrument PI 500 done. communication default values: ID : 1 (1-247) Baudrate: bps (1200,2400, 4800, 9600, 19200, bps) Parity: even (none, even, odd) Stoppbit: 1 (1,2) Supported are following functioncodes: Function code 03: Read Holding Register Function code 16: Write multiple Register Register Mapping measuring values: Address No.of Byte Data Type Description Defau lt Settin g Read Write Float Temperature R [ C] Float Temperature R [ F] Float Relative Humidity R [%] Float Dew Point R [ Ctd] Float Dew Point R [ Ftd] Float Absolute Humidity R [g/m³] Float Absolute Humidity R [mg/m³] Float Humidity Grade R [g/kg] Float Vapor Ratio (Volume) R [ppm] Float Saturation vapor pressure R [hpa] Float Partial Vapor Pressure R [hpa] Float Atmospheric DewPoint R [ Ctd] Float Atmospheric DewPoint R [ Ftd] Remark for DS400 / DS 500 / Handheld devices - Sensor Datatyp: Data Typ R4-32 match with Data Type Float Unit /Comment 7

9 CALIBRATION/ADJUSTMENT From the manufacturer According to DIN ISO certification of the measuring instruments we recommend regular calibration and, if necessary, adjustment of the instrument by the manufacturer. The calibration cycles should fit your internal scheme. In the course of the DIN ISO certification, we recommend for FA 510 a calibration cycle of one year. If requested we can carry out the calibration on your premises. WARRANTY If you have reason for complaint, we will of course repair any faults free of charge if it can be proven that they are manufacturing faults. The fault should be reported immediately after it has been found and within the warranty time guaranteed by us. Excluded from this warranty is damage caused by improper use and non-adherence to the instruction manual. The warranty is also cancelled once the measuring instrument has been opened provided this is not described in the instruction manual for maintenance purposes. This is also the case if the serial number has been changed, damaged or removed. The warranty time for FA 510 is 12 months for the instrument and 6 months for accessories if no other terms are agreed upon. Warranty services do not extend the warranty time. If in addition to the warranty service necessary repairs, adjustments or similar are carried out, the warranty services are free of charge but there is a charge for other services such as transport and packing costs. Other claims, especially those for damage occurring outside the instrument are not included unless responsibility is legally binding. After-sales service after the warranty time has elapsed We are, of course, there for you after the warranty time has elapsed. In the case of function faults please send us your measuring instrument with a brief description of the defect. Please also indicate your telephone number so that we can contact you if necessary.
